My invention relates generally to weighing vices embodied in the platform mounting scales and more particularly to those of the means ofmy invention. type embodying a platform on which a person Referring specifically to the drawings in I stands in Ord r to b w i h d, which similar reference characters designate It is a purpose of my invention to provide a similar parts in each of the several views, my

The vertical portion 14 of the platform is provided along its front and rear sides with races 21, whereas other races 22 and 23 are secured respectively to the rear wall of the standard S and to the inner side of the cover plate 16. Balls 24: are interposed between and work in the races for co-aotion therewith in mounting the platform for vertical movement while positively guiding the platfoi'm a ainst an' tiltin movements all with C r C 7 but negligible friction, to the end that re gardless ofthe location on the foot plate 18 at which a person stands to be weighed, the vertical movement of the platform will remain accurate to insure the true weight of the ard S. A second lever 31 is pivoted adjacent one end at 32 on an upright extension of the bracket 29, and connectmg the levers :47 and 29 is a link To the free end of the lever 29 is pivotally connected the usual spring mounted draw rod 34: operatively connecting the platform with the indicating mechanism of the scale through the medium of the above described lever system which ordinarily is located beneath the platform and multiplies the vertical movement of the latter as will be understood.

It will be manifest from the foregoing description that I have provided a weighing scale,*the base portion and platform of which are of simple and compact construction and structurally characterized and correlated in amanner to preclude injury to passersby coming in contact with these parts of the scale, and that furthermore the manner in which the platform is mounted insures accurate vertical movement of the platform when depressed by the weight of a person standing on the platform at any possible location.

Although I have herein shown and described only one form of weighing scale embodying my invention, it isto be understood that various changes and modifications may be made therein without departing from the spirit of the invention and the spirit and scope of the appended claims.

I claim:

1. A weighing scale having a base, and a platform on the base, the base and platform having sloping sides, with the sides of the platform forming continuations of the sides of the base when the platform is unloaded and co-actlng to define inclined approaches to the top of the platform extending at a relatively acute angle from and with respect to a surface on which the base is supported.

2. A weighing scale having a base provided with an opening and side walls sloping downwardly and outwardly from the marginal edges ofthe opening, and a platform mounted for vertical movement in the opening, and having side walls sloping outwardly and downwardly to form continuations of the respective side walls of the base when the platform is unloaded.

3. 'A weighing scale having a base, a weighing platform on the base, and means on the base and platform co-acting to provide inclined approaches to the top of the platform extending at a relatively acute angle from and with respect to a floor or other surface on which the base is'rested.

4. A weighing scale having a weighing platform, and means co-acting with the platform to define inclined approaches to the top of the latter, extending at a relatively acute angle from and with respect to a floor or similar surface on which the scale is supported. V

5. A weighing scale having a base, a hollow standard rising from the base, a platform having a horizontal portion correlated with the base and a vertical portion extending into the standard, and means co aeting with the vertical portion of the platform to mount the platform for rectilinear movement vertically. I

6. A weighing scale having a base, a hollow standard rising from the base, the base projecting laterally from the standard and having an opening and the front wall of the standard having a slot extending into the opening, a platform having a horizontal portion disposed in said opening and a vertical portion insertable through said slot into the standard, a closure for the slot, and means co-acting with the vertical portion of the platform to mount the'platform for vertical movement. i

7. A weighing scale having a base, a hollowstandard rising from the base, the base having an opening and the front wall of the standard having a slot extending into the opening, a platform having a horizontal portion disposed in said opening and a vertical portion insertable through said slot into the .standard,'a closure for the. slot, and antifriction means on the standard, vertical portion of the platform and closure, co-acting to mount the platform for vertical movement.

8. A weighing scale having a base, a platform correlated with the base,,the scale being characterized by the absence of mechanism beneath the platform to enable the latter to be disposed at a relatively low height from a floor or other surface on which the base is supported, means for mounting the platform for movement vertically, and means correlated with the platform to define inclined approaches to the top of the latter, extending at a relatively acute angle with respect to the surface on Which the base is supported.

9. A Weighing scale having a base, a platform correlated with the base, the scale being characterized by the absence of mechanism beneath the platform to enable the lat ter to be disposed at a relatively low height from a floor or other surface on which the base is supported, means for mounting the platform for movement vertically, and sloping sides on the base and platform forming continuations of each other when the platform is unloaded, and providing inclined approaches to the top of the platform, eX- tending at a relatively acute angle from and with respect to the surface on which the base is supported.

10. A weighing scale having a base; a platform; means for mounting the platform for movement vertically; mechanism for trans ferring vertical movement of the platform to an indicator, said mechanism being disposed at a location other than beneath the platform, so as to enable the latter to be at arelatively low height from a surface on which the base is suported; and means defining inclined approaches to the top of the platform, extending at a relatively acute angle from and with respect to the surface on which the base is supported.

11. A weighing scale having a base; a platform; means for mounting the platform for movement vertically; mechanism for transferring vertical movement of the platform to an indicator, said mechanism being disposed at a location other than beneath the platform so as to enable the latter to be at a relatively low height from a surface on which the base is supported; the base and platform having sloping sides forming continuations of each other when the platform is unloaded, to provide inclined approaches to the top surface of the platform, extending at a relatively acute angle from and with respect to the surface on which the base is supported.
